The temperature guage on my 1.4TDi is behaving erratically at the moment.
When I am idling in traffic the guage needle drops to 60deg. but when I am moving at a regular speed it moves up to 90deg. its normal operating temperature. On long runs it some tiomes drops back down to 60 for a few minutes then goes back up to 90 again. Which is exactly the opposite from what I would expect. The engine has never overheated and seems to be running perfectly normally. Oh by the way I have declined an offer from my local dealer to do a check and report on the problem for £80.00. Hope someone out there may be able to throw some light on the problem.
